Kvass is like a bread kombucha and is super refreshing. The darker you get the bread and the more molasses is used instead of sugar, the more beer-like your kvass will end up. I have subbed sugar for molasses and it still works out, it's a pretty foolproof recipe in terms of getting something tasty. This recipe can be scaled up or down as necessary.




  1. Toast the bread until it is really dark, like burnt dark. I toasted my bread twice at the highest setting and it was very burnt around the sides. The darker you go, the more dark in color and flavor your kvass will be.
  2. Put around a quarter of your water on heat and dissolve honey and sugar. You don't want all your water hot, just this little bit.
  3. Add the rest of your water and molasses to the mixture and stir it in.
  4. Place the mixture into your primary fermentation vessel and add the toasted bread and yeast/sourdough starter.
  5. Let it sit out of direct sunlight. Fermentation should start beginning after around 24 hours.
  6. Let it ferment for around four days, give or take depending on taste and how sweet you want it.
  7. Once to your liking, strain the bread from your kvass. Do this slowly, as you may also have sediment at the bottom and we want to keep that out, as well.
  8. At this point, you can drink it.
  9. If you want to do a secondary fermentation for carbonation and/or flavoring, bottle it in your secondary fermentation vessels with your added flavorings. If doing this, be sure to take care that you are burping your vessels often if using glass, or monitor your plastic containers for excess fermentation. When you're happy with the carbonation, refrigerate them.
